Katy Perry, Alicia Keys, Brad Paisley and more to play at inaugural events

As we get closer to President Barack Obama's second inauguration, celebrity acts continue to sign on to take part in the festivities. The latest boldface names to officially join in the action are Katy Perry, Alicia Keys, Usher, Brad Paisley and the cast of "Glee."

That crop of singers, along with Stevie Wonder, Smokey Robinson, Marc Anthony and John Legend, Nick Cannon, fun., and Mindless Behavior are expected to make appearances at various events, including the Kids' Inaugural on Saturday, Jan. 19, and the official inaugural balls that take place the evening of Jan. 21.

The Kids' Inaugural is hosted by first lady Michelle Obama and Dr. Jill Biden and is part of their commitment to military families; the concert honors and celebrates the service and sacrifice of the U.S. military and their families. Inaugural officials have not indicated which performers will be at the Kids' Inaugural, and which will perform at other balls.

For those seeking out public performances, the actual inauguration ceremony on the West Front of the U.S. Capitol on Jan. 21 is the best bet. Beyonce will be there to perform the national anthem; James Taylor is scheduled to sing "Shower the People;" Kelly Clarkson will sing "America the Beautiful."
